Karrueche Tran is rumored to be furious with Chris Brown after reportedly misleading her about his feelings for Rihanna when they first started dating.

According to HollywoodLife, the "Loyal" singer "gassed" Tran up like no other when they first met, assuring her that he was no longer hung up on his on-again, off-again ex-girlfriend, Rihanna.

But just this week, during the height of yet another one of their public blowups, a source close to Brown told Hollywood Life the R&B heartthrob was still in love with Rihanna when he took up with Tran.

It all now has the 27-year-old model telling friends her relationship with Brown was bound to fail because it was all built on dishonesty. The two formally split several weeks ago when it was revealed Brown had fathered a child with another woman without her knowledge.

"He told Karrueche everything a girl wants to hear -- how beautiful she is, how much he cared about her and wanted to get to know her and her mind, how he didn't want it to just be about sex -- all of that," a source said of their early days together. "Chris [misled] Karrueche from the get go. He made her fall in love with him."

The source added Tran was always suspicious Brown might still harbor feelings for the "Diamonds" singer. Reportedly, there was even a time when he picked her up blasting Rihanna's music on his car stereo.

"Even worse,Rihanna still had clothes and personal items at Chris' house," the source added. 

Meanwhile, the 26-year-old Brown has been telling friends he feels Tran should be more appreciative of the lifestyle he's given her and be willing to show just a little bit more gratitude.

"Chris feels that, for the most part, he's been incredibly loyal to Karrueche," a source added. "He's given her a life that she would never have had without him. He doesn't want to fight with her [and] he loves her."
